The happy path is only a demo
In payment operations, network failure and retries are the product. If a green UI is enough to update the order, you will double-fulfill or lose evidence.
A safer order of operations
- Create an intent with a clear reference.
- Adapter normalizes provider evidence.
- Match on amount, reference and time window.
- Commit state once (idempotent).
- Deliver a signed webhook; retries stay audited.
Language boundary
Public copy says confirmation and reconciliation. It does not claim custody, transfer or licensed processing. This remains research/prototype, not a live payment product.
Do not trust the green button. Trust evidence and the idempotency key.
